Completely fun post here: How low - YouTube Since I had my video camera out recording the mustang idle issues, I thought i'd take an SPL video of my single 12" TC sounds SVS sub in a 12" wedge box (From parts express). The sub was a free upgrade when I bought a PC12+ tube sub from them, so I had an extra one lying around. I know it's silly, but I like how the JVC reads the song title "How Low", the SPL meter reads "lo", and then the bass hits. About half-way through I turned up the volume a bit more, and hit 120+ dB. I don't know how high, as I maxed out the rat-shack SPL meter. It's impressive until I consider that I used to run twin Eclipse 8812 subs in there, and they hit 136.4dB at the dB drag races. Now those subs in my home theater, along with the SVS tube sub, and twin DefTech BP2002TLs (12" sub built in) for a total of 5 subs. Plus buttkickers in the seats. Why yes, I do like bass.
